know, major medical conditions, although there is a bit of a loophole, because it does say other conditions. if the doctor thinks that marijuana is beneficial for you, they write a card and you can go to the dispensaries. and if you can't get to a dispensary, there is a sort of hardship law, you can grow your own marijuana. >> you mentioned the medical difficulties, people who studied it for nausea, for example, and studies on chemotherapy or hiv-aids. but also pain, you and i talked about this last time, using a pain medication. in medicine, you want to know, does it work, is it safe, is it more effective than other things out there. how would you say it compares to other medicines? >> well, it is different, some pains are not treated well by opiates, pins and needles that you can get as a side effect of other medications. it is a sort of neuropathic pain.
